uitextview が Google API を使用して現在の場所を読み込むときに UIActivityIndicatorView を停止する方法。
ここに私のコードがあります:
@implementation ViewController
@synthesize loctxt;
- (void)viewDidLoad {
loctxt=[[UITextView alloc]initWithFrame:CGRectMake(10, 50, 220, 30)];
loctxt.backgroundColor=[UIColor whiteColor];
loctxt.delegate=self;
[self.view addSubview:loctxt];
locbtn=[[UIButton alloc]initWithFrame:CGRectMake(240, 50, 40, 30)];
[locbtn addTarget:self action:@selector(clickToGetLocation)forControlEvents:UIControlEventTouchUpInside];
locbtn.backgroundColor=[UIColor grayColor];
[locbtn setImage:[UIImage imageNamed:@"sst14.gif"] forState:UIControlStateNormal];
[self.view addSubview:locbtn];
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
}
- (void)clickToGetLocation {
spinner = [[UIActivityIndicatorView alloc] initWithFrame:CGRectMake(0,100, 20, 20)];
[spinner setActivityIndicatorViewStyle:UIActivityIndicatorViewStyleGray];
[self.view addSubview:spinner];
**[spinner startAnimating];**
AppDelegate *delegate=(AppDelegate *)[[UIApplication sharedApplication]delegate];
NSString *urlString = [NSString stringWithFormat:@"http://maps.google.com/maps/geo?q=%f,%f&output=csv",delegate.latitude, delegate.longitude];
NSError* error;
NSString *locationString = [NSString stringWithContentsOfURL:[NSURL URLWithString:urlString] encoding:NSASCIIStringEncoding error:&error];
NSLog(@"%@",locationString);
locationString = [locationString stringByReplacingOccurrencesOfString:@"\"" withString:@""];
**self.loctxt.text=[locationString substringFromIndex:6];**
//if i use code [spinner stopanimating]; here then the indicator does not appear
}
